1. Introduction. Ultrahighperformance concrete (UHPC) is a relatively advanced cementitious composite with superior mechanical properties, excellent durability, and good impact resistance [1], [2], [3].The low watertobinder ratio ( ∼ ) and high cement content are often used to achieve ultrahigh strength, resulting in high cost, energy consumption and intensive CO 2 emission [4].

Abstract Thermal mechanisms of microstructural refinement in steels were reviewed. These include thermal cycling, martensite process, and static recrystallization (SRX), in which the dominant stage of microstructural refinement is governed by an annealing treatment of a deformed or an undeformed material. Recent progress in grain refinement by thermal cycling for the bodycentered cubic, face ...

The commercially available class F fly ash (FA) and ultrafine fly ash (UFFA) were used as partial replacements in cement. The UFFA had 18% more amorphous content compared to FA. After 28 days of curing, the 100 mm cube samples were immersed in a 3% sulphuric acid concentration (H 2 SO 4, pH≈3) and % nitric acid concentration (HNO 3, pH ...

Supplementary cementitious materials (SCM) are increasingly used in concrete for economical and environmental reasons. However, the durability of reinforced concretes against, for example, corrosion induced by carbonation varies. Here, the phase assemblage of various cement pastes with/without SCM (slag, fly ash and metakaolin), carbonated in accelerated conditions (% CO 2 and 65% RH) or ...

Although ultra highperformance concrete (UHPC) has great performance in strength and durability, it has a disadvantage in the environmental aspect; it contains a large amount of cement that is responsible for a high amount of CO 2 emissions from UHPC. Supplementary cementitious materials (SCMs), industrial byproducts or naturally occurring materials can help relieve the environmental burden ...

Cement is the most widely used building material, and particle size distribution is an important factor affecting the performance of cement. This paper studies the physical properties, mechanical properties and drying shrinkage of cement under different grinding time. The results show that with the increase of grinding time, the particle size distribution of cement tends to move towards small ...
